Intangible Assets and Goodwill
Intangible assets consist of the value of core deposits and mortgage servicing assets and the excess of purchase price over fair value of net assets (goodwill). Core deposits are stated at cost less accumulated amortization and are amortized on a sum of the years digits basis over a period of one to ten years. See Note

acquisition.
 
Mortgage servicing rights are recognized as separate assets when rights are acquired through purchase or through sale of mortgage loans with servicing retained. Servicing rights acquired through sale of financial assets are recorded based on the fair value of the servicing right. The determination of fair value is based on a valuation model and includes stratifying the mortgage servicing rights by predominant characteristics, such as interest rates and terms, and estimating the fair value of each stratum based on the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as costs to service, a discount rate, and prepayment speeds. Changes in fair value are recorded as an adjustment to earnings.
 
The Corporation performs a “qualitative” assessment of goodwill to determine whether further impairment testing of indefinite-lived intangible assets is necessary on at least an annual basis. If it is determined, as a result of performing a qualitative assessment over goodwill, that it is more likely than not that goodwill is impaired, management will perform an impairment test to determine if the carrying value of goodwill is realizable.

About Goodwill & Intangibles Disclosures

Goodwill and intangible asset disclosures reveal the premium paid in acquisitions and how management assesses whether that premium retains its value. Since goodwill is no longer amortized under US GAAP, the annual impairment test is the only mechanism that adjusts carrying values downward — making the assumptions behind that test critically important for investors.

Key signals: a history of goodwill impairments suggests management consistently overpays for acquisitions. Watch the gap between reporting unit fair value and carrying amount — when fair value exceeds carrying amount by less than 10-20%, a small decline in business performance could trigger a write-down. For finite-lived intangibles, examine useful life assumptions across customer relationships, technology, and trade names; aggressive estimates inflate near-term earnings. Compare total intangibles-to-total-assets ratios against peers to assess acquisition dependency. Rising goodwill as a percentage of equity can signal balance sheet fragility.
